Endangered and Threatened Wildlife and Plants; Determination of Endangered Status for Two Insects From the Santa Cruz Mountains of California

The U.S. Fish and Wildlife Service (Service) determines endangered status pursuant to the Endangered Species Act of 1973, as amended (Act), for the Mount Hermon June beetle (Polyphylla barbata) and Zayante band-winged grasshopper (Trimerotropis infantilis). These two insect species are restricted to the Zayante sand hills ecosystem endemic to inland marine sand deposits in the Santa Cruz Mountains of Santa Cruz County, California. The species are in danger of extinction principally because of ongoing and future habitat loss to sand mining and urban development. This rule implements Federal protection and recovery provisions afforded by the Act for each of these animals. The proposal to list the Santa Cruz rain beetle (Pleocoma conjungens conjungens) as an endangered species is being withdrawn and will appear in a separate section of this publication.
